Kingdom Come: Deliverance, a game built with CryEngine looked like it was going to be a fantastic game to have on Linux, but the developers have told me it "is not possible technically".
When asked directly about what's happening with the game coming to Linux:
Unfortunately I can´t verify this right now, as we don´t know. We still want to publish it on Linux too, but right now it is not possible technically. We are waiting and hoping for a solution for this. We can neither say if it will come for Linux, nor it will not come.
The situation about this topic is kind of tricky.
But thank you for your request.
Their Kickstarter still to this day lists Linux as a platform.
A real shame, as the game looks incredible. I hope they find a way, and I hope they make an official announcement about this instead of us chasing them down for details.
